CTURE. PLUGGER.

SPECIFICATION forming part of Letters Patent No. 616,660, dated December 27, 1898. Application filed eptemhe'r 12,1898. $e1ial No. 690,733. (No model.)

To to whom it may concern.-

Be it known that L'Cvsus P. GIFFORD, a citizen of the United States,residing at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Bicycle-Tire-Puncture Pluggers; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.

My invention relates to improvements in bicycle-tire-puncture pluggers and material to be used therewith; and it consists, substantially, in constructing a strip of flexible rubber substantially triangular in shape and adapted to be folded back upon itself and inserted into a puncture in a bicycletire and in a tool for inserting the same, as hereinafter fully set forth and explained, and illustrated in the accompanying drawings, in which' Figure 1 is a View in elevation of my improved plugger with the rubber plug placed thereon ready to be inserted into a puncture. Fig. 2 is a sectional view of the same, showing the plugger with the jaws open. Fig. 3 is a like view of the same, showing the jaws closed. Fig. dis a detail view of the jaws detached. Fig. 5 is a detail view of the slide operating on the jaws. Fig. 6 is a perspective view of the flexible rubber plug. Fig. 7 shows the same folded for insertion into the tire.

In the drawings thus illustrating my invention, A is the handle of the plugger, within which a removable tube B telescopes. In the head a of the handle A is secured the end 61 of one of the jaws D D, so that the outer end (1 thereof projects from the central part of the open end a of the handle A, as illustrated in Figs. 2 and 3. To this jaw D the jaw D is pivoted by means of a pivot (1 so as to swing thereon, as illustrated in Figs. 2 and 4.

In one side of the rear portion of the jaw D there is a depression (1 and on the opposite side thereof an extension (Z and the outer ends (1 d of both jaws are cut away, so as to form when closed together a conical point d, having an opening 01 therein adapted to receive the triangular piece of rubber F, Figs. 6 and 7.

Over the jaws D D, I place a slide, Fig. 4:, the inner end of which is provided with a rec- 5 5 tangular portion 6, which passes over the portions of the jaws D D in the rear of the rivet d and operates on the depression (1 and the projection 61* on the jaw D to open the jaws, as illustrated in Fig. 2, when it is moved outward and close them, as illustrated in Fig. 3, when moved backward. On the outer end of the slide E there is a circular piece 6, provided with an open slot 6 which passes over the outer portions of the jaws D D and allows 65 them to be opened, as illustrated in Fig. 2. The circular portion 6 is of suitable size to engage the inturned end Z) of the telescoping tube 13, so that when the strip of rubber F is folded back through the opening d the ends f f thereof will ass over the circular portion 6 of the slide and be engaged between it and the inturned flange b of the tube B, so that when the tube B is pushed back into the handle A the rubber strip is stretched and the jaws D D closed, as illustrated in Fig. 1, and if then inserted through a puncture in a tire, with the rubber so stretched, until the outer end of the telescopic tube B is nearly in contact with the outer surface of the tire and the instrument withdrawn the rubber will remain in the puncture, completely closing it.

Having thus described my invention, so as to enable others to construct and use the same, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. The combination in abicycle-plugger, of a handle, hinged jaws in said handle, a slide on said jaws, and a section adapted to pass 0 over the jaws and slide, substantially as and for the purpose set forth.

2. The combination in a bicycle-plugger, of a handle, hinged jaws secured in said handle,

a slide on said jaws adapted to open and close the jaws, a circular end on the outer end of said slide, and a tubular section adapted to pass over said jaws and engage the circular end of the slide thereon, substantially as and for the purpose set forth.

3. The combination in a bicycle=plu I00 gger, of

a tubular handle, a pair of hinged jaws therein, the rear end of one of said jaws being secured to the rear end of the handle, and the outerends of said jaws forminga conical point with an opening therein when closed, a slide moving to and fro on said jaws and adapted to open and close them, a circular slotted end on the outer end of said slide, and a tubular section adapted to telescope into the handle and pass over said slide and engage the circular slotted outer end thereof, substantially as and for the purpose set forth.

i. The combination of a bicycle-plugger, substantially comprising hinged jaws, aslide operating on said jaws, a slidingsection adapted to engage said slide and a rubber strip, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

CYRUS P. GIFFORD.
